8 Claims. (Cl. 206-58) This invention relates generally to cartons, and more particularly to a carton of the type formed from a onepiece blank of paperboard, designed to encase a roll of sheet materim and permit dispensing of said material in controlled lengths.

One object of the present invention is to provide a carton of this type which includes simple and improved roll positioning means for rotatably mounting said roll within the carton.

Another object of this invention is to provide in a carton of this type which is collapsible, roll positioning means formed from the carton walls, which roll positioning means also afford locking means for maintaining the carton in assembled condition.

A further object of this invention is to provide a carton of this type adapted to hold the roll securely for shipping, and when open to display the entire length of the roll material retained therein, affording access to the roll for dispensing of said material without removal of the roll from the carton.

Still another object of this invention is to provide a carton of this type having means for access to the roll of material and affording a double cutting edge adjacent said access means and cooperating therewith, for dispensing said material in controlled lengths.

According to the general features of this invention the improved dispensing carton comprises a one-piece blank which is foldable to provide a three-sided or triangular shaped carton having multi-ply end walls. The multi-ply end walls are formed from overlapping end flaps hingedly connected to the side wall panels, having portions thereof displaced inwardly to provide positioning members upon which a hollow roll of sheet material may be rotatably mounted. The positioning members are formed by displacing aligned central portions of the overlapping end flaps inwardly, said displaced portions cooperating to interlock the end flaps whereby to hold the set-up carton in assembly. One side wall is cut and perforated in a manner to permit a portion thereof to be displaced inwardly about the hinged connection with an adjacent side wall, thereby to provide access to the roll material and a double cutting edge at said hinged connection. 'Said displaceable portion of the one side wall is formed substantially coextensive with said roll whereby displacing said portion displays the entire length of the roll material and affords access thereto for dispensing said material along the double cutting edge. This particular carton construction provides packaging means suitable for receiving and retaining a roll of material compactly for shipping, and when opened displaying said roll of material and affording means for dispensing same in controlled lengths, it being intended that the roll retaining means innited States Patent clude locking means for maintaining the carton in as- 2,935,192 Patented May 3, 1960 Figure 1 is a plan view of the one-piece blank used in making a carton according to the teachings of this invention.

Referring now to the drawings, and particularly to Figure 1, the reference numeral 10 indicates a sheet of suitable material, such as paperboard, cut and scored to provide a one-piece blank, bendable, in a manner to be described, to form a carton adapted for the purposes herein set forth. As shown, the blank is formed to provide serially connected main panels 12, 14, and 16, and glue flap 1%, said panels 14 and 16, and panel 16 and flap 18, being hingedly connected through simple scores, indicated at 15 and 17, respectively, and panels 12 and 14 being hingedly connected through a cut-score 13, the purpose of which will be discussed later. Also to be discussed later and in conjunction with the cut-score 13, panel 14 has a portion 20 thereof defined by perforations 21 and said cut-score, said perforations permitting rupture of the panel therealong and displacement of said portion from the plane of the panel about the cut-score.

As indicated, panel 12 has end flaps 22 hingedly connected at the end edges 23 thereof, panel 14 has end flaps 25 hingedly connected at the end edges 26 thereof, and panel 16 has end flaps 28 hingedly connected at the end edges 29 thereof. The end flaps 22 and 25 are triangular in shape and constitute full end flaps, i.e. when the carton is in set-up or assembled condition each of said flaps spans an area coincidental with the carton end opening defined by the main panels or side walls 12, 14, and 16 (see Figures 3 and 5), while end flaps 28 are partial end flaps and need only extend sufficiently to function as a. dust seal. It is to be noted that panel 16 and the adjoining end flaps 28 are scored centrally thereof as at 31, in a line parallel with the previously described scores 13, 15, and 17, to permit assembly of the carton to a partially set-up or collapsed condition, as will now be described.

As shown, glue flap 13 is coated with an adhesive 33 and as viewed in Figure 1 downward movement of the upper portion of panel 16 and the adjoining portions of the flaps 28 about the score 31 through degrees, and downward movement of panel 12 and the adjoining flaps 22 about the cut-score 13 through 180 degrees, places flap 18 in a position lapping panel 12 and through said adhesive, secured thereto. The blank thus folded and glued provides a partially set-up or collapsed carton (Figure 2) which in such fiat form is highly suitable for shipping, storing, or handling prior to complete set up and assembly. It will be appreciated that inward pressure exerted simultaneously along score 31 and cutscore 13 will cause outward movement of the panels or side walls 12, 14, and 16 to an open or tubular position, as indicated by dotted line 35. In such open position the carton interior is accessible for filling or placement of an article to be packaged. I

The folding inwardly of end flaps 28, 22, and 25, in that order,to close the open ends of the carton, provides a set-up carton as shown in Figure 3. The carton in this form is triangular in cross-section, and, as shown,

said carton is spatially disposed to offer the edge formed" by cut-score 13 as an apex. It should be understood that although the carton embodiment illustrated is ,of 'triangular shape, such shape is not material to the invention described. It will be obvious in the description that follows that the number of main panels or side walls, and the subsequent shape of the carton, i.e., triangular, rectangular, hexagonal, etc., is a matter of choice and design which does not effect the cooperation'of elements as recited herein. I

Referring once'again to Figure 1, the full end flaps 22 and 25 have central portions thereof, 37. and 38, respectively, cut and scored in a manner as to permit displacement of each said portion from the plane of its flap, for a purpose to be described later. tab 37 of flap 22 is formed, as-shown, in substantially rectangular shape, having three sides thereof defined by a cut 40 with the fourth side being a score, indicated at 41. The central portion or tab 38 of flap 25, defined by cut 43 and score 44, is formed to provide a main portion 45 of substantially rectangular shape having wing portions 47 hingedly connected thereto, as by scores 48'. It is noted, that whereas tab 37 is hingedly connected to flap 22 at the tab side 41 remote from cut-score 13, tab 38 is hingedly connected to flap 25 at its tab side 44 nearest said out score 13. The relation of opposite hinge connections for tabs 37 and 38 is significantin the end flap interlock for carton assembly, as will now be described.

As shown in Figure 1, it is intended that tab 37 and the main portion 45 of tab 38' be similar in shape and size, and complementary in arrangement, so that when the carton is set-up as shown in Figure 3, with flap 25 overlying flap 22, the main portion 45 of tab 38 will overlie and be aligned with the tab 37. Finger pressuref applied to the portion 45 of tab 38 to displace same inwardly about score 44 will also cause displacement inwardly of tab 37 about score 41. It is noted that such displacement inwardly results in the tab portion 45 moving through flap 22 at the opening 50 therein afforded by the simultaneous, displacement inwardly of tab 37, said opening being of width sufficient to accommodate only the main portion 45, whereby the wing portions 47 are wiped or folded inwardly about their scores 48 to permit such displacement, and thereby forming a U-shaped' projection. Complete displacement of tab portion 45 to the horizontal position of Figure 6 disposes wing portions 47 entirely within the carton, whereupon passingfree of the opening said wing portions swing outwardly tending to their original planar disposition. Such outward movement of the wing portions, best shown in Figure 5, prevents withdrawal of the tab 38 through opening 50 and constitutes the previously mentioned end flap interlock. Tab 37 having been pivotally displaced by the inward movement of tab 38, tends to return to its original planar position, anddoes in fact move to the Wedging position indicated in Figure 6, comprising not only a dust seal for the carton interior but also a support for tab portion 45, as will be explained. It is noted that the wedging disposition of tab 37 with tab portion 45 also provides an end flapinterlock, and the wedging action increases as, and when, tab 37 is forced outward.

It is apparent that the end flap interlock as above described is an adequate lock to maintain carton assembly regardless of the carton contents. However, such lock construction was designed for and, because of its par ticular configuration extending inwardly, is ideally suited for the packaging of roll material having a hollow core. The packaging of such roll material is illustrated. in Figures 4, 5, and 6, and contemplates a carton construction providing the described lock at both ends thereof.

The central portion or Referring to Figure 4, a typical article to be packaged is shown as a roll of sheet material 52. As seen in Figure 6, said roll terminates adjacent the carton end wall comprising flaps 22 and 25, and has a hollow core 53 into which the tab 38, formed to present an inverted Ushaped projection, extends. As shown in Figure 5, the hollow core inner surface is contacted at several points by tab 38, but the primary support is afforded along the main portion edges coincidental with scores 48. While the tab 38 through its wing portions 47 is sufficient to position and retain the roll material, it is noted that additional support therefor is obtained through the tab 37 which underlies the main portion 45 of tab 38.

' port of the roll material to maintain it in a position free from contact with the carton side walls 12, 14, and 16, thereby affording roll supporting and retaining means which will permit rotation of said roll, for a purpose now to be described.

As previously mentioned, it is contemplated that. the roll material will be suitable for dispensing, and in conjunction with the provision of a confined but rotatable roll of material the carton is constructed to afford access to said roll without removal of same from the carton. Said access means is provided by rupture of panel 14 along perforations 21 and displacement of panel portion 20 inwardly about cut-score 13. To facilitate complete displacement of portion 20 to a position adjacent side wall 12, as shown in Figure 5 said portion is provided with a centrally located score 55 parallel to cut-score 13, which permits sufficient distortion of said portion to manipulate same over the roll material. a In this position, and because of the cut-score 13, a double edge or blade 56 is formed at the carton apex, comprising a serrated or saw-edge surface suitable for cutting through material brought smartly against it. It is noted, that panel portion 20 depends pivotally from cut-score 13 and is of a sufficient length relative to the disposition of roll material 52 as to be restricted thereby in. movement from the operative position shown. In addition, the tendency of panel portion 20 to return to its original planar position results in said portion remaining in frictional contact with the roll of material 52, thereby offering resistance to inadvertent unrolling or loosening of the roll material. In

' this respect, it is also noted that wing portions 47 of tab i material either clockwise or counter clockwise, as viewed in Figure 5, it is preferred that the roll to be rotatable clockwise in dispensing so as to permit withdrawal of the material along the panel portion 20, as indicated by dotted line 57. In this manner, the material to be removed can be brought sharply about the cutting edge assuring full contact of the material upon the cuttting edge surfaces. Also upon severance of a portion of the material the remaining unrolled material 'willfall free upon the roll proper, in a position easily accessible without manipulation of said roll.

From the foregoing description it is apparent: that through a single gluing step the one-piece blank of F g,- ure 1 is formed to provide the collapsed cartonof Figure 2, which upon being expandedjas indicated, affords an open-ended carton suitable for receiving anarticle flaps and displacement inwardly of central portions thereof provides r011 positioning means disposed within the adjacent end of the hollow core. The roll positioning means while rotatably mounting the roll, also afford the means for interlocking the end flaps, thereby securing the carton in assembled condition. A portion of a carton wall is displaceable to provide access to the roll material, and adjacent said access is formed a cutting edge for severing the material from the roll in desired lengths.

While the foregoing description sets forth the invention in specific terms and in conjunction with a preferred embodiment, it is to be understood that many variations and modifications may be resorted to without departing from the broad aspects of the invention as defined in the appended claims.
